When I incepted this thread I never thought that it would receive as many views or replies as it has. Which goes to show that there was clearly the big elephant roaming the room with most of us trying to ignore it.
To those that it effects then, good luck deciding which way to jump!
Lastly Saabdriver, I would not worry about the AB package, Hunold has been the master of divide and conquer, having AB, DBA, LTU and GMX all working for the same parent and all on differing contracts, some represented and others not, the writing is on the wall.
As more 737s and the future 787s arrive they will be operated by the lowest bidder, in the very same manner airlines like QF ransom off their regional flying to the lowest bidder among wholly owned daughter companies.
On top of that the FR & 4U contracts with dedicated days off allow you to at least plan some days off in advance where the AB guys are regularly positioning all over Germany by air and ground just to cover crew “vacancies”.
